Specificationof Letters Patent.

Patented July 1-8, 1916.

Application filed August 8, 1914. 7. Serial No. 855,821.

Toall whom it may concern:

Be it known that I, CARL (l. THOMAS, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in Fluid-Distributing Devices, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, form-ing ,a part ofthis This invention relates to fluid distributing devices.

It has among its objects to provide a device for distributing fluid in one or more shifting streams of any desired range and volume whereby said device may be utilized in various ways, for example,as a sprinkler, mixer or agitator.

Afurther object is to provide a device so constructed as to insure'uniformity of distribution.

Other objects and advantages will hereinafter appear.

The accompanying drawing illustrates several embodiments of the invention which will now be described.

In the accompanying drawing, Figure 1 is a longitudinal sectional view of a device suitable for lawn sprinkling and the like; Fig. 2 isa sectional view on lines -22, Fig. 1; Fig. 3 is a sectional view of a modified form of device suitable for various purposes, as for use as an agitator in a tank or the like; and, Fig. 4 is asectional view of another modified form of device also adapted to various uses.

Referring to the device shown in Fig. 1, the same includes two telescoped tubular members 1 and 2 closed atone end. The inner member 2 is threaded into an elbow 3 ha-vingan inlet 4: in communication with the interior of said member 2. The member 1, on the other hand, is revoluble being provided at one 'endnwith a cup-bearing 6 in the elbow 3 and being revolubily supported at itsoppositc end on a spindle 7 extending axially through the member 2. The member 1 is held against axial movementin one direction by the bearing 6 and in the opposite direction by nuts 8 on the spindle 7.' The member 1 is provided on opposite sides with rectilinear slots :9 extending sub stantially the entire length thereof and provided with oppositely flared edges or lips 10. The member 2 on :the oth'er hand, is provided with a spiral slot '11 which intersects the slots 9 in the outer member at a plurality of points to produce discharge apertures of restricted area. The number of discharge apertures may, of course, be varied by varying the pitch of the spiral slot or the number of rectilinear slots in the outer member and the size of the discharge apertures may spirally slotted member 2. Thus by rotating the spindle 7 the member 2 may be axially contracted or permitted to axially elongate for regulating the width of the slot 11 as desired. Lock nuts 14 are pro- .vided to secure the spindle against accidental rotation and the extremity 15 of the spindle is pointed to provide a spike for supporting the device in a vertical position.

As will be apparent the device operates as follows: When fluid is admitted into the elbow .3 it passes into the member 2 and thence through both members 2 and 1 at the points of intersection of the slots 9 and 11 thereby producing a number of separate streams. Then as the fluid escapes it impinges the :fiared edges 10 of the slots 9 and revolves the vouter member 1 whereby the discharge openings are shifted along the line of the spiral slot 11. In consequence the several streams take spiral paths, or in other words, said streams shift both radially and axially of the tubular members. Thus assuming that the slots in both members are of uniform width throughout it will beappare'nt that there will be a resultant uniformity in the volume and velocity of each stream throughout the operation of the device and as already set forth the volume ofthe streams may be readily regulatedzby axial contraction .or extension .ofthe member 2 through the medium of the spindle 7 Referring-now to the device shown in Fig. '3, .the same includes two sets of telescoped tubular members 16 and 17 similar to those previously described. In this instance,-

and the outer members 16 non-revoluble. The outer members 16 are fixed in opposite walls of a casing 20 while the members 17 are revoluble within the members 16, bearing sleeves 21 being inserted therebetween. Fluid is admitted to the casing and thus to the distributing members through a tube 22 which forms a support for the casing 20. The device is arranged for suspension in a turn. or the like and is bodily revoluble about the supporting tube 22-, a suitable packing device 23 being provided to prevent the escape of fluid between so id casing and said tube. The casing may be rotated by any suitable means through the medium of external gear teeth 2 1 or any other preferred means. Thus the tubular members are provided a rotatable movement in a plane parallel to their respective axes and through the medium of pinions 25, 26 and 27 the inner tubular members 17 are simultaneously revolved about their respective axes. The pinions 25 and 27 are fixed to the two tubular members 17 and mesh with the common pinion 26 fixed to the stationary tube 22.

Referring now to the device shown in Fig. 4, the same includes two telescoped tubular members 30 and 31 supported by a casing 32. In this instance both members30 and 31 are revoluble and in opposite directions and both are provided with spiral discharge slots of the same pitch. In consequence, the telescoped members provide a plurality of diamond-shaped discharge openings which shift axially of the distributing members upon relative rotation thereof. More specifically describing the structure, the outer member 30 is revolubly mounted in a bearing 33 provided in the left hand wall of the casing, while the member 31 is revolubly mounted in a bearing 34 in the right hand wall of the casing. The casing in this instance is designed to be stationarily mounted whereby the right hand end of the inner tubular member 31 may be extended into a stationary supply pipe 35, a suitable packing joint 36 being provided to prevent the escape of fluid between the members 31 and 35. For revolving the members 30 and 31 the same are provided with pinions 37 and 38 respectively which mesh with a common pinion 39 fixed to a shaft 10 operable from any suitable source through a pulley 4.1 or other device. As will be apparent, with the arrangement illustrated the members 30 and 31 will, upon rotation of the shaft 10, be revolved in opposite directions with the results aforesaid.

It will be seen in view of the foregoing description that in all three modifications of the fluid distributing device at least one of the tubular members is constructed to other while fluid is passing 'therethrough,

the rotation of the outer tubular member in the modification shown in Fig. 1 being produced by the movement of the fluid itself acting on the angularly disposed openings 9 and 10 of said member.

In a companion application, filed August 8, 1914:, Sr. No. 855,822, I have claimed a fluid distributing device such as the member 2 of Figs. 1 and 2, or the member 17 of Fig. 3, or the members 30 and 31 of Fig. 4:, consisting of a tubular body one end of which is circumferentially complete, and the other end of which is closed, said body being provided with a helical slot intermediate its ends; therefore I do not claim such invention herein.

What I claim as new and desire to secure by Letters Patent is:

1. A device of the character set forth, comprising two closely fitting tubular members, one within the other, and having intersecting openings angularly related and of which at least one is a slot disposed in a general direction longitudinal of the member in which formed, at least one of said members rotatable with respect to the other, and constructed to rotate continuously while fluid is passing therethrough, in combination with means for supplying fluid under pressure to said tubular members.

2. A device of the character setforth, comprising two closely fitting tubular members, one within the other, and having longitudinally extending openings angularly related, at least one of said members rotatable with respect to the other and constructed to rotate continuously while fluid is passing therethrough, in combination with means for supplying fluid under pressure to said tubular members.
